PAIL-TRAY.

Specification of Letters Patent.

Application filed May 29, 1911.

Patented Feb. 6, 1912. Serial No. 630,058.

To all whom it may concern:

Be it known that I, EDWARD L. BAILEY, a citizen of the United States, residing in the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain Improvements in Pail-Trays, of which the following is a specification.

My invention is designed to provide pail trays of improved construction whereby blanks can be formed with. the minimum waste, the trays can readily be erected from the flat blanks, and the parts of the trays can be securely interlocked in their erected relation with the resulting strength desired.

The characteristic features of my improved trays are illustrated in the accompanying drawings, in which- Figure 1 is a blank made in accordance with my invention, two of the peripheral sections being interlocked in the erected and overlapping relation contemplated; Fig. 2 is a perspective view of a tray erected from the blank shown in Fig. 1, separators being shown for forming several compartments therein, and Fig. 3 is a sectional elevation of a pail filled with the trays.

The blank, as illustrated in Fig. 1, has the polygonal center 1 adapted to form a tray bottom symmetrical with reference to a center and defined by the scoredv lines 2 of uniform length and related as intersecting chords of a circle. Peripheral sections 3 extend beyond the center 1, being defined by the parallel lines 2 and 4: and the radial lines 5 passing through the respective intersections of the lines 2 and the lines 4. These sections, being separated by cutting through the material on the lines 5, are regular trapezoids or dovetails, expanding from the bottom and adapted to be erected to the angular relation with the bottom that may be required in the sides of the tray formed thereby, in order to fit the conical interior of the pail, the adjacent parts of the sections having overlapping triangular portions adapting them to be interlocked together so as to provide a secure lap joint. The respective outer corners of the peripheral or side sections 3 are provided with the angular through cuts 6 and the dovetails or outwardly expanding lugs 7 adapted to be passed upwardly through the slots of the adjacent sections when such sections have been brought to the erected overlapping relation. The lugs 7 are formed by the V- shaped notches 8 intersecting the lines 4 so that such lugs shall lie at the corners of the sections between the radial dividing lines 5 and be thrust upwardly through the slots 6 toward the lines 4; by the resiliency of the material.

In erecting the trays the sections 3 are turned on the lines 2 and parts thereof comprising the lugs 7 are brought within the parts of the respective adjacent section containing the slots 6, the sections are sprung so that the lugs can be passed through the slots and, having been passed therethrough, the natural disposition of the paper board to assume its original flat form maintains the engagement.

It will be understood that in this construction no creases are required in the sections forming the sides of the tray as the construction and the elasticity of the paper board of which the device is composed permits such sections to spring to the extent desired for conformation with the pail.

These trays may be divided into' several compartments to hold assorted articles by providing them with separators comprising paper board strips 9 secured together in the cross form shown in Fig. 2, the strips being suitably half the depth of the trays and supporting paper disks 10 dividing the trays horizontally into upper and lower compartments.

Trays 11, of the foregoing character and of suitably graduated diameters, are inserted one on top of another, when filled, in a pail 12.

Having described my invention, I claim:

A pail tray having a polygonal bottom and side sections integrally formed there-' with and divided by lines diverging from the center of the bottom, each of said sections having near one side edge an angular slot, and at the other edge an outwardly eX- panded lug formed by a notch in the outer edge 01": the section, the lug of each section interlocking with the adjacent slot of another section.

In Witness whereof I have hereunto set my name this 25th day of May, 1911, in the presence of the subscribing witnesses.

EDWARD L. BAILEY. Witnesses:
